Reversible Motor Drivers (Single Motor)
BH6578FVM BD7931F
General Description
The BH6578FVM and BD7931F are reversible motor
drivers with a wide output dynamic range, with power
MOS used for the output transistor. The motor drivers
can be set to four output modes 1) forward (normal)
rotation, 2) reverse rotation, 3) stop (idling or OFF)
and 4) brake using 2 logic inputs.
Features
 Wide dynamic range loading driver with MOS
output, RON = 1.0Ω (Top + Bottom)
 With loading driver voltage setting terminal
 Built-in Thermal Shutdown Circuit (TSD)
